Had a ford with the 1.0 eco boost as a rental in Atlanta a few years ago during a work trip. With two grown men (neither of us very large) and a couple carry on bags, the car actually struggled to maintain speed on over passes in the city. It was terrible. That being said, I have a 2.7 eco boost in my personal 2019 F150 and it’s a phenomenal engine with zero problems.
A tiny turbo engine is bound to have problems after a while because it is overstressed. Even if the engine stays together, the turbo will go even with 3k oil changes. Replacement cost is around $5k.
2.4 Theta motor owner here. (2011 sonata) I currently have 318k miles, originally motor, lack of maintence (motor has never been opened). Just oil changes, sparkplug replacement, air filter changes. Oil pan gasket changes. I treat mine like a 90s mazda owner. Just keep up with the oil and it's good to go
The Kia engines are a weird one... If you don't get one that had debris in the crankshaft, they'll go forever with proper maintenance including induction services. I work at a Kia dealership, and I see both. We are replacing hundreds of engines a year, but at the same time I see cars roll in with their original theta ii engines with way over 200,000 miles. Kinda crazy.
If they got their QC under control I’d have considered purchasing one. Similar story with Nissan and their transmissions. Instead I bought a Corolla, which I’m actually enjoying.
I have 2011 sonata with 2.4. Meticulously maintained but It was burning oil like crazy. Knowing that they wouldn’t do anything about it, i ran it low on oil until it locked up. I did keep used oil in my trunk and as soon as it failed, i added used oil before towing it to the dealership. Got a replacement engine. You have to play it safe and not give dealership any reasons to decline warranty. Especially for a crappy engine.
The 4.6L iron block V8 in my 2009 Grand Marquis has 240,000 on the clock, runs like new, doesn't burn oil and actually gets good mileage on the highway. The same company built an engine with a timing belt inside the engine. Anybody who thought putting a timing belt inside an engine should be put in jail.
I refuse to believe the QR25 is terrible, the amount of these on 3 bald tires, a spare donut and everything held together with duct tape while doing 40 over speed limit at all times tells me its the best engine ever produced.
Nissan: we’re Japanese in every way except the good ones. Terrible reliability, fugly copycat Japan style, unethical transmission designs, and abysmal performance…
I think that was thrown in for outrage engagement. It's the only engine on this list that has examples that have lasted a million miles. I see these engines with over 200k miles all the time, sometimes over 300k miles.
So . They're just topping up the oil and coolant everytime they stop. And they're already DONE, replacing the timing sensors every year, so they just let it ride rough as hell. It's many small things that suck on these engines. Electrical most of the time.
I now change the oil in my 2013 Kia Optima LX 2.4 non-turbo every 4 months or 3000 miles. Used to take it to the Kia dealer every 5000 miles when I was driving 50 miles a day on an interstate highway to work. The engine performed perfectly.....I think getting the oil up to operating temp for an extended period is crutial...it boils off any blow-by products and prevents them from contaminating the oil to any great degree. The dealer used a blended oil....I now use a full synthetic oil and Kia/Hyundai filter. I do not drive much since I retired. Kia recommended 5w20 oil but as I crossed 75,000 miles I switched to 5w30 and the engine seemed to run quieter and a little smoother. I plan on changing the plugs very soon. I think 12 years is long enough on the original plugs. The timing chain cover is starting to seep oil but not enough to be significant between changes. Dealer wanted 1500 dollars to reseal the cover...I imagine if the cover is removed it would be best to replace the timing chain and guides. Another 500?? I am 76 yo and will be doing it myself. The major reason I have stopped using the dealer for general maintenance is that I do not like the fact that no matter what the situation, even with an appointment, I will have to wait for an oil change a minimum of an hour and a half and am not allowed to observe. It is worse than going to the doctor. If you do your oil changes yourself just keep good records and change it often. Going on 79000 miles on my Optima and am satisfied with it.
My father in law's Kia engine blew up at 86k miles after running rough for a while. A long distance trip from Cincinnati to Canton blew up the engine. He haggled with Kia for a month before it agreed to replace the engine. Hopefully the new engine was assembled without metal debris and will last a few years. On the other hand, my mom's 2013 Elantra with the 1.8 liter engine ruins perfectly after 100k miles.
You aren't in the clear yet, but if your Optima is a K VIN that means it was made in Korea and those Thetas seem to have reasonably better reliability than the Georgia built version.
BladeCenter good for you sir. My ciusin just bought her son a show room /shoffered elantra 2023 with 5000 miles and they added the insurance pack that includes the oil change. I should've said bring it by me when they bought it I've got plenty oil for 10 years Just buy the filter 🙃 oh well lol
Can’t believe how colossal of a failure the Hyundai/Kia 4 cylinders are. Pair that with the poor maintenance from their owners and they are all destined for super premature failures. Insane that they used that engine for over a decade, especially when their entire sales tactic was the warranty they fight so hard to honor.
I have a 2017 Sorento with the V6 and the engine has run well and I ve been happy. However I would never replace it with a new model as you have to get it with one of the 4 cylinders now.
Dirt and remains from the assembly is not an engine problem. Its an assembly problem. Combustion fuel injection is something all cars have nowadays. But it is not a good idea.
But all engines don't have debri problem. This is a competitive industry. Debri is a result of carelessness in manufacturing plants. It can result in catastrophic failure. Look what happened to Toyota Tundra. That is why it is important to critique.
I just sold my old 2012 Elantra. The engine had a horrible rattle that sounded like a tin can. When the issue first started at around 60k miles it would only happen when you’d do a cold start and wouldn’t sound so bad once the engine had warmed up a bit but by the time I got rid of it it didn’t matter. I remember seeing letters from Hyundai in the mail all the time about recalls, and had to replace my steering column at around 75k/80k miles. It still got me through my 20s and the majority of my 30s though so despite all the BS I’m grateful it wasn’t worse
My 2013 Hyundai 2 l turbo is still working fine. Good fuel economy, lots of power, doesn't burn oil. I added a catch can. When I first heard of debris left in the engine, I added rare earth magnets to the drain plug. Hyundai called mine in. The cheack was a free oil change and they cut the filter open. They replaced my magnets. No debris was found. I do oil changes more often than spec'ed. And oil over "SN" spec has detergents for carbon in the oil from the GDI, to increase timing chain life.
The way that Kia gets you is that while the engine is covered, the hoses and belts are not. When I got my Sportage back after a new engine was installed, I also had a bill of $700 for the hoses and belts that needed replaced.🤬. While the Kia is a fairly comfortable and easy to drive vehicle, this will be the last Kia/Hyundai that I will own.
The Nissan ka24de is a very good engine. I've owned hard body trucks with this engine and both went over 290,000 miles. Don't know why it was mentioned.
@@ArrowGearhead I have a Nissan Frontier with the 2.5 liter engine(I think it is the QR25DE). It has gone 105,000 miles without issue. I think it is the stuff placed around the engine, not the engine itself. I have read about some Nissan car models that have had screws come loose in the intake system and get sucked into the engine and other stuff.
Direct injection is part of the problem because the engines don't have port injection Port injection will clean the intake valves and it's better at keeping the Pistons clean they have problems with the PCV systems they also 9 out 10 of them have a high pressure fuel pump cam driven and if the fuel pump starts to leak into the engine and you can dilute your fuel or your oil with fuel and therefore you're going to have diluted oil getting up into the piston rings and with the heat that these engines create they end up sticking and then you're piston rings aren't doing the job to keep everything clean you know separated yeah new cars are pain especially with all the computers they have in them and they track everything you do
You are probably thinking of the Ecoboost 2.0T. It isn't a bad motor if you respect it, but LR owners likely don't. The head and block are fragile, so it needs to gently warm up before you give it the 15lbs of boost (kind of common with turbos). You also can't go 10k-15k miles on oil on an oil-cooled turbo engine for multiple reasons.
While telling us about the #2 engine, the 2.4 Tigershark , more than half the video loops shows a grand Cherokee, which has never used the 4 cyl Tigershark, but the fine 3.6 Pentastar V6. Plus the no longer built original Cherokee that was available with the 2.4 TS, that was after I test drove one to buy was awful and underpowered, especially in a 4x4/awd version! But I bought a very nice running 3.2 Pentastar V6, a smaller bore 3.6, tuned for mileage in the lighter Cherokee that ran great in my opinion, with a 9 speed automatic, that unfortunately came to a final drive that was so high the 9 th gear was never used till 80-85 mph! That if Jeep had offered a lower differential setup the power to the ground would have been even made a quicker vehicle! Possibly getting more highway mileage! Due to the use of 9th gear at legal cruising speed. Today I’m driving my second 3.6 Pentastar in a new Gladiator with 8 speed automatic that’s fantastic for what it moves, a 4,500lbs + brick, that still gets me over 20 mpg up to 70 mph! Or overall average of 18+!
I have a 2022 Jeep compass with a 2.4 tigershark engine. I change the oil every 5,000 miles with vavoline synthetic motor oil. It uses no oil between changes mantain this engine it will give you years of service.
I have a 2021 Cherokee with the same engine..I've heard there were problems with the earlier engines but the problems were solved in the 2018 and up years.
Sorry for your ear bro I will tune it down next time so that it can be able to watch my video without requiring safety earplugs. Thank You for watching and the feedback
I have experience with two of these engines. I owned a 2015 Fiesta with the Fox motor. It was previously my dad's. When he owned it, the head gasket blew. When I owned it, the cam phasers failed (and were on backorder for months) and the turbo blew. This was between 52k miles and 71k miles. I sold it and got a honda and have never looked back. My work vehicle is a Promaster City with the Tigershark. The engine got replaced under warranty at 72k miles for burning over a quart of oil a week. Fun fact: the 9 speed autos in those are junk too. It got replaced at 35k miles in mine.
Totally agree about qr25de nissan, u should add about the notorious spark plug seals that integrated into the whole valve cover, meaning that u should replace the whole valve cover if u want to replace the spark plug seals. And for 2 decades this problems still persist and never corrected by nissan. I once owned a nissan T30 qr25de less than 100.000 kilometers its already had a major problems
I got lucky with my old SER spec v qr25de, the previous owner did a cat delete, and it did consume a screw from the butterfly valve, but only took out the spark plug and then left the combustion chamber. That was a decade ago and the car is still running and to my knowledge it doesn't burn oil. I also now have the 1.8 MPI version of the 2.0nu, which are known for piston slap and oil ring issues. My "fix" is using the best fuel and oil available and a good wot pull once a day to clean up carbon. I'm at 191,000kms on the motor now, hoping to get to 300,000 at least
had the qr25 in my 2005 spec v step 1 cut the balance shaft chains or if youre bored remove them entirely this is a couple hours work at most step 2 proper block back stainless exhaust. frankly this should just be standard on all cars who isnt sick of rusty exhaust? car and engine ran a treat and were still going strong in 2020 when i sold it
That's the thing, I got my grandfathers car as my first car. (I'm 16) When he passed at the end of this summer, he left It to me because he knew I would take care of it, and it's been great so far. It just hit 65,300 miles, so I've put about 3,100 miles on it so far. No problems on its Theta ii turbo 4cyl engine. It's a 2015 sonata sport 2.0t. I check the oil about every 2 weeks, no excessive oil consumption like some people say. Also, personally, the 2.0t sonatas are underated. They can be a LOT of fun with 245 hp stock.
I'm learning how to work on it in my high school auto shop class. it's not too bad to work on. I'm also thinking about doing some slight tasteful mods, magnaflow catback, HKS ssqv blowoff valve, AEM cold air intake, lap3 protuner, Enkei TSV 18x8.5 +38 aftermarket rims, ADDW1 dual inlet catch can and maybe even some adjustable coilovers to lower it an inch or two.
I had a 1.0 ecoboost fiesta. I had 175,000 trouble-free miles and have no doubt it would have gone to 200k if two deer didn't total the car. I read the owners manual and it said 7500 mile oil changes. I thought about a little 1.0 pumping it's heart out and decided to do oil changes every 3500-4000 miles. Not one issue with the car.
They made changes to the engine in 2021 to adress issues. I drive 1.2 non-turbo with currently 74 000km on the clock. I hope it last for at least 2 more years. Then it's payed and mine and I can sell it. 😊
The QR25DE engine issues were only for a few years (‘02 - ‘04 early ‘05). Later iterations fixed the issues, I had a ‘05 Sentra SE-R Spec V that had zero engine issues and I currently have family members with high mileage Altima’s (‘10, ‘11, ‘13, ‘21) with no engine problems.
4:39 isn't that Fiat Doblo? Also, Stellantis is rolling with 1.2 Puretech - unreliable construction, problems with oil consumption, timing chains sh*tting themselves after not long distances...
IMPRESSED! Finally agree with one of these lists. The Nissan qr (quality reduced) probably the best of the lot sadly. The turbo turd 1.0 isn't worth fixing if anything goes wrong. The theta and nu haveade me a lot of money. It's sad, almost all of these have 1 major problems. Their manufacturers cheap out in the wrong areas. But hey they don't want the car to last longer than the warranty. If that was really true there would be no 5.3l Chevy. They make their money upfront or on things other than the engine and for the most parts transmissions. As a mechanic the most consistent engine to go over 300k iss the 5.3l Chevy. Too bad they won't be making them for too much longer with their fuel consumption issues. I can guarantee that every single one of them they ever make will be bought immediately upon announcement if their discontinuation. And then the appreciation $ begins there is really only one way to kill the Chevy.$6plus a gallon fuel.
Tellingly, ALL of the engines on this list mainly affect the low(er) cost car models on the market. I can't help but wonder if it's deliberately encouraged by regulators to push marginal buyers out of the market entirely. At the very least, it proves that low end buyers don't matter to the OEMs or government regulators.
Talking about the 1.0L EcoBoost's cool tech and then immediately saying 'wet timing belt' 😂😂😂 That's the kind of 'cool tech' that manufacturers want to avoid at all costs for the reasons you said
I think all the manufacturers right now are in the process of trying to make every new engine make the current and future worst engines list. It is clear now the manufacturers are ok with compromising reliability and longevity for performance, yes you can get 350hp from a 2.7 inline 4 or 550hp from a 3.0 inline 6 or 1000hp from a 6.2 V8 but you can't have that and get high miles out of it, big lazy V6 and v8s last forever but there is no money in cars lasting forever. Cars are now built to make it through the warranty and be disposed of and that's sad and pretty much a terrible recipe for low carbon footprint. You can take an old gas guzzling car from way back and drive it forever and even with more fuel used and more emissions you still leave a way lower carbon footprint than a new car. And older cars are more recyclable where they have less plastics and toxic materials to dispose of.
I do not understand how these "engineers?" can make this stuff. Any of us with real world experience in repairs knew the wet belt Eco-boost coud not last! For the exact reason they show here. Heat and oil? On RUBBER? It was only a matter of tiem till the belt started to degrade.. The shame is, with an exterior belt, the 1.0 could have been a GREAT little engine
One of these things is not like the others. The QR25DE engine is one of the more reliable engines you can get in a vehicle. I'll admit their introduction was rocky in 2002-2006 because they had oil consumption problems but Nissan reworked the engine for 2007 and they have been solid ever since. Hell, the million mile Frontier still had its original QR25 engine.
Those 2.4 Tiger Shark engines in Dodge Darts are hitting 300,000 miles with no problems when you take care of them, so this video claiming they're bad engines is putting out the wrong info to people. ua-cam.com/video/fRvfrtPR1Bw/v-deo.htmlsi=3xMx3wPd0qHeauL3
Ford ecoboost 2 cylinder belongs in a yard tractor/lawn mower not a car. Avoid anything with a turbo because when they break it gets real expensive real fast.
Almost all large commercial trucks have turbos and go a million miles plus with no problems. They are a very proven reliable technology. You should only hope the engine lasts as long as the turbo.
I can't imagine who came up with a wet belt there have been a couple things that are totally stupid ideas in car engines and the biggest idea has to be wet belts and a list of least favourite cars Kia Hyundai Jeep Fiat Ford and Nissan just don't buy them and save you'd self money just buy something decent with a good record of reliability
I’d like to know how squirrels are getting under the hood. Where you add oil, there is nothing but pine cones, leaves and whatever else they eat. I have to be careful cleaning it because I don’t know what that crap could do if it got in the engine. This is the first time it happened. What a mess.
If I had to choose between a Ford Ecoboost, any EV, or being torn up by vicious dogs, I’d ask to see the dogs before I decided. Modern automotive engineers should lose a finger or two each time they design a garbage drivetrain that could likely destroy the financial health of the second owner that thinks their lower mileage vehicle will outlast the payments. They end up paying off a car loan long after the unfixable car went to the salvage yard.
Pretty sure the QR is dead, and has been for a few years. Last thing to have it was the T32 Rogue; the T33 and L34 switched to the PR25DD, though it's only a couple numbers different from the QR on paper.
What is it with 2.4 litre engines? I’ve got a 2.4L in my 2011 GMC Terrain. It does worry me. The only major problem so far is a cam sensor that went south. 400$ repair. I don’t know if that’s a good, normal or excessive price.
@ 30$ and I spent 400$ that’s not even including the flatbed tow rig ( mine is AWD) I’m also getting peeved with the change oil soon light coming on and this is 20 minutes after an oil change. My mechanic even showed me how to reset the oil remaining after doing an oil change. I’ll never understand GM. Good luck with your Equinox . Take care.
I had a qr25de in a nissan xtrail. Had an issue with the valve cover leaking. Nissan fixed some of the vibrations by adding a third engine mount...on top of the valve cover. So to change the valve cover (normally maybe 30 min job) took me a week after disassebling the engine mou t to drop the engine down to get to the bolt on the valve cover. Plus the egr valve and the power steering tank. Then the pcv valve snapped and that was 300 dollars australian and 3 month wait. Ended up getting one off ebay for 60 dollars. Horrible gremlin of an engine. Oh and without premium fuel it would only run on 2 cylinders and stall out.
I have a Focus with1.0 ecoboost and 200.000 km, with no problem, no power loss, hardly any oil use. So I am curious about the real data of failures, instead of just repeating what other youtubers say (who don 't own a 1.0 ecoboost either).
A lot of complaints, recalls, and lawsuits are not without a reason. Premature failure in an ownership of someone you know is also a good source. I never owned one with any ecoboost.
The QR is a great engine. The throttle body screws was an overblown problem that wasn't really as big as it seemed. It was easily preventable with 45 minutes of labor and the balance shafts really don't ever fail unless you don't maintain the engine. The cat design is stupid, along with like nearly every other Nissan model at the time, and the valve covers DO leak omg do they leak. You have to be careful in your choice of valve covers with them. They have little M6 screws that hold the valve cover onto the engine as well that need to be torqued juussttt right because you will strip out the threads easily. Ask me how I know. Overall, it's a great engine, makes insane power for what it is, sounds awful but puts the power down so who cares. I loved my QR and am hoping to buy another one again, if they're maintained right and you loctite those 8 screws you're golden Plus, the 2005+ (I think, I could have the years wrong) went away from the variable length intake runners so you don't need to worry about the screws
Where are the car companies getting their engineers, makes you wonder, running a timing belt through oil, sounds good, but do they test out any of their "great ideas", GDI, sounds good, but unless you are a meticulous owner about maintenance, and realistically, there's not many, GDI is destined to cause a premature death of your engine, the so called engineers have literally ruined modern vehicles, too much tech, without any reliability.
Ok dude no. The QR25 is not the only engine that uses a Maniverter (Catalyst thats attached to the exhaust manifold) hell almost every 4 cyl engine does this. Also most also scavenge exhaust. This was a issue with the converters not the engine itself…… the QR25DE also does not have the screws that fall off the throttle plates……. Every engine can have timing chain stretch these motors get abused… and sure yeah the valve cover has to be swapped if the tube seals fail… a hour job at most…. The other engines are common surprised you did not cover the 2.0 ecoboost that had a stupid block deck with the cut that causes head gaskets to fail where the only remedy is just replacing the short block……..
I NEVER subscribe to asks first before earning - EARNING it. Only lazy incompetent people ask first. Real people earn it with good, meaningful content.
*except the 2nd Gen 2.7. Seriously, those things are great. The weak link is the wet belt driven oil pump, which I'm pretty sure Ford added (the first generation had a chain driven oil pump) because they weren't having enough service/replacement profit.
Who would've ever thought that making an overly complicated 4 cylinder produce more power than it is safe to make. Then putting it in a big heavy vehicle would cause problems? Oh yeah, everybody who understands how engines work. It's more efficient to have a big engine barely working than a small engine working overtime. Less stress, less maintenance, longer life, and happier owners. This is why I won't own a modern vehicle. I'll stick with my old V8s. Lugging down the highway at 1500 rpm, while the smaller engines around me sound like they're ready to explode. And most probably are
The 1.6 Gamma/Smarstream is a solid little simple engine that's mildly overbuilt for the rated power and with correct maintenance is extremely reliable.
I own a 2017 accent with the 1.6 gamma engine It's my daily commuter to work, 180000km and running strong and no oil consumption, but i change oil every 6000 kms using full synthetic oil, gets 50 mpg if driven nicely. Great little engine
My nissan has 130k carefree miles ,doesnt burn oil ,maybe a half a qt every 5k between changes i havent even done the tune up stuff yet and it still purrs ,oh yeah its a 1.6 not that 2.5 so nissan did good here

I now change the oil in my 2013 Kia Optima LX 2.4 non-turbo every 4 months or 3000 miles. Used to take it to the Kia dealer every 5000 miles when I was driving 50 miles a day on an interstate highway to work.

BladeCenter good for you sir. My ciusin just bought her son a show room /shoffered elantra 2023 with 5000 miles and they added the insurance pack that includes the oil change. I should've said bring it by me when they bought it I've got plenty oil for 10 years Just buy the filter 🙃 oh well lol
Can’t believe how colossal of a failure the Hyundai/Kia 4 cylinders are. Pair that with the poor maintenance from their owners and they are all destined for super premature failures. Insane that they used that engine for over a decade, especially when their entire sales tactic was the warranty they fight so hard to honor.
The best part is that people still buy Hyundai/Kia products like crazy in spite of their terrible reputation.
I have a 2017 Sorento with the V6 and the engine has run well and I ve been happy. However I would never replace it with a new model as you have to get it with one of the 4 cylinders now.
I was told the hyundai engine problem was mainly with American manufactured engines
Poor quality control
Dirt and remains from the assembly is not an engine problem. Its an assembly problem. Combustion fuel injection is something all cars have nowadays. But it is not a good idea.
But all engines don't have debri problem. This is a competitive industry. Debri is a result of carelessness in manufacturing plants. It can result in catastrophic failure. Look what happened to Toyota Tundra. That is why it is important to critique.
Still the engine !
Wet belts ? Ridiculous
My car has a wet belt 🤡💀
I just sold my old 2012 Elantra. The engine had a horrible rattle that sounded like a tin can. When the issue first started at around 60k miles it would only happen when you’d do a cold start and wouldn’t sound so bad once the engine had warmed up a bit but by the time I got rid of it it didn’t matter. I remember seeing letters from Hyundai in the mail all the time about recalls, and had to replace my steering column at around 75k/80k miles. It still got me through my 20s and the majority of my 30s though so despite all the BS I’m grateful it wasn’t worse
Rain, dust and dirt. Engineers have never heard of this stuff.
Quality control is done by engineers
@@ArrowGearhead No. MANAGERS
They'd prefer to talk about noise, vibration, and harshness.
My 2013 Hyundai 2 l turbo is still working fine. Good fuel economy, lots of power, doesn't burn oil. I added a catch can. When I first heard of debris left in the engine, I added rare earth magnets to the drain plug. Hyundai called mine in. The cheack was a free oil change and they cut the filter open. They replaced my magnets. No debris was found. I do oil changes more often than spec'ed. And oil over "SN" spec has detergents for carbon in the oil from the GDI, to increase timing chain life.
You are one of the lucky ones. I wish you many more miles. For those with the bad engines, the frustration must be unbearable.
You handled it the smart way, good to hear this.
@@jamesgullo8240 : Thanks guys. I know 4 people with the 2L turbo and 2.4 L One did get a new engine from Hyundai.
Nissan engine "inhaling" its own exhaust?!?! Engine commiting suicide!!!😂😂😁 Just can't take it anymore!!!😉
Think EGR
The way that Kia gets you is that while the engine is covered, the hoses and belts are not. When I got my Sportage back after a new engine was installed, I also had a bill of $700 for the hoses and belts that needed replaced.🤬. While the Kia is a fairly comfortable and easy to drive vehicle, this will be the last Kia/Hyundai that I will own.
The Nissan ka24de is a very good engine. I've owned hard body trucks with this engine and both went over 290,000 miles. Don't know why it was mentioned.
I have talked about the QR25DE here in this video, completely different engine. KA24DE is a great engine. Thank you for mentioning
@@ArrowGearhead I have a Nissan Frontier with the 2.5 liter engine(I think it is the QR25DE). It has gone 105,000 miles without issue. I think it is the stuff placed around the engine, not the engine itself. I have read about some Nissan car models that have had screws come loose in the intake system and get sucked into the engine and other stuff.
Direct injection is part of the problem because the engines don't have port injection Port injection will clean the intake valves and it's better at keeping the Pistons clean they have problems with the PCV systems they also 9 out 10 of them have a high pressure fuel pump cam driven and if the fuel pump starts to leak into the engine and you can dilute your fuel or your oil with fuel and therefore you're going to have diluted oil getting up into the piston rings and with the heat that these engines create they end up sticking and then you're piston rings aren't doing the job to keep everything clean you know separated yeah new cars are pain especially with all the computers they have in them and they track everything you do
You missed out the current 2L Landrover engine
You are probably thinking of the Ecoboost 2.0T. It isn't a bad motor if you respect it, but LR owners likely don't. The head and block are fragile, so it needs to gently warm up before you give it the 15lbs of boost (kind of common with turbos). You also can't go 10k-15k miles on oil on an oil-cooled turbo engine for multiple reasons.
While telling us about the #2 engine, the 2.4 Tigershark , more than half the video loops shows a grand Cherokee, which has never used the 4 cyl Tigershark, but the fine 3.6 Pentastar V6. Plus the no longer built original Cherokee that was available with the 2.4 TS, that was after I test drove one to buy was awful and underpowered, especially in a 4x4/awd version! But I bought a very nice running 3.2 Pentastar V6, a smaller bore 3.6, tuned for mileage in the lighter Cherokee that ran great in my opinion, with a 9 speed automatic, that unfortunately came to a final drive that was so high the 9 th gear was never used till 80-85 mph! That if Jeep had offered a lower differential setup the power to the ground would have been even made a quicker vehicle! Possibly getting more highway mileage! Due to the use of 9th gear at legal cruising speed. Today I’m driving my second 3.6 Pentastar in a new Gladiator with 8 speed automatic that’s fantastic for what it moves, a 4,500lbs + brick, that still gets me over 20 mpg up to 70 mph! Or overall average of 18+!
Right
Thank you so much for sharing
Thats like bragging how rich your fat girlfriend is. It's still a stellantis vehicle🤮
I have a 2022 Jeep compass with a 2.4 tigershark engine. I change the oil every 5,000 miles with vavoline synthetic motor oil. It uses no oil between changes mantain this engine it will give you years of service.
Thank you for sharing
I have a 2021 Cherokee with the same engine..I've heard there were problems with the earlier engines but the problems were solved in the 2018 and up years.
Stellantis's 1.2l wet belt 3 cylinders deserves to be on this list imo ^^
Thank you for sharing
There is Part - II of this video. Check it here: ua-cam.com/video/edNKJ2jyeeU/v-deo.html
Indeed, but at least they went back to chain driven cams.
Most engines use direct injection these days
Yeah dude, thanks for the ear shaking bell ring during the video
Sorry for your ear bro
I will tune it down next time so that it can be able to watch my video without requiring safety earplugs. Thank You for watching and the feedback
I have experience with two of these engines. I owned a 2015 Fiesta with the Fox motor. It was previously my dad's. When he owned it, the head gasket blew. When I owned it, the cam phasers failed (and were on backorder for months) and the turbo blew. This was between 52k miles and 71k miles. I sold it and got a honda and have never looked back. My work vehicle is a Promaster City with the Tigershark. The engine got replaced under warranty at 72k miles for burning over a quart of oil a week. Fun fact: the 9 speed autos in those are junk too. It got replaced at 35k miles in mine.
You are lucky to get it under warranty. Baby it religiously. Thank you for sharing your experience
@@ArrowGearhead nah it's a company rig I beat the piss out of it😂
My 2012 3.7L 6-spd manual Mustang without a turbo is the most reliable vehicle I’ve had in many years!
And it sticks to the road beautifully…!!
I've got a 2000 BMW e39 with an M52 engine, 445000+ km later it still runs like new
Yeah, 1 in a million.
Totally agree about qr25de nissan, u should add about the notorious spark plug seals that integrated into the whole valve cover, meaning that u should replace the whole valve cover if u want to replace the spark plug seals. And for 2 decades this problems still persist and never corrected by nissan.
I once owned a nissan T30 qr25de less than 100.000 kilometers its already had a major problems
Thank you for adding
T30 is a beutiful vehicle, I love it
Hyundai doesn't use the theta II engines in any vehicle instead for the 2.0l they use the Nu .
Most bmw engines
In Poland we are calling any N engine from BMW as "N jak Nie kupuj" - "N like No buy" :D
BMW = Break My Wallet
@@mmllmmll22 pol: BMW = Będziesz Miał Wydatki. eng: BMW = you'll have expenses. Sorry, the acronym gets lost in translation.
I got lucky with my old SER spec v qr25de, the previous owner did a cat delete, and it did consume a screw from the butterfly valve, but only took out the spark plug and then left the combustion chamber. That was a decade ago and the car is still running and to my knowledge it doesn't burn oil.
I also now have the 1.8 MPI version of the 2.0nu, which are known for piston slap and oil ring issues. My "fix" is using the best fuel and oil available and a good wot pull once a day to clean up carbon. I'm at 191,000kms on the motor now, hoping to get to 300,000 at least
Great job
You have impressive miles on it
You forgot the TSI 2.0 vw total garbage, timing chain and tensioner issues 2008 through 2017 and today's aren't any better
Yeah, especially the earlier one's have a lot of complaints
had the qr25 in my 2005 spec v
step 1 cut the balance shaft chains or if youre bored remove them entirely this is a couple hours work at most
step 2 proper block back stainless exhaust. frankly this should just be standard on all cars
who isnt sick of rusty exhaust?
car and engine ran a treat and were still going strong in 2020 when i sold it
The 2.0L Theta II i in my Veloster N and many other Velsoter N's is really robust.
Congrats, you're among the lucky ones.
That's the thing, I got my grandfathers car as my first car. (I'm 16) When he passed at the end of this summer, he left It to me because he knew I would take care of it, and it's been great so far. It just hit 65,300 miles, so I've put about 3,100 miles on it so far. No problems on its Theta ii turbo 4cyl engine. It's a 2015 sonata sport 2.0t. I check the oil about every 2 weeks, no excessive oil consumption like some people say. Also, personally, the 2.0t sonatas are underated. They can be a LOT of fun with 245 hp stock.
I'm learning how to work on it in my high school auto shop class. it's not too bad to work on. I'm also thinking about doing some slight tasteful mods, magnaflow catback, HKS ssqv blowoff valve, AEM cold air intake, lap3 protuner, Enkei TSV 18x8.5 +38 aftermarket rims, ADDW1 dual inlet catch can and maybe even some adjustable coilovers to lower it an inch or two.
Another engine that really SHOULD be in this list is the GM 3.6 V6.
I had a 1.0 ecoboost fiesta. I had 175,000 trouble-free miles and have no doubt it would have gone to 200k if two deer didn't total the car.
I read the owners manual and it said 7500 mile oil changes. I thought about a little 1.0 pumping it's heart out and decided to do oil changes every 3500-4000 miles. Not one issue with the car.
U fotgot the verry infamous stellantis/psa 1.2 puretech its a verry much worse engine compared to the ford ecoboost
Should be renamed the Stellantis 1.2 L Purestench.
They made changes to the engine in 2021 to adress issues. I drive 1.2 non-turbo with currently 74 000km on the clock. I hope it last for at least 2 more years. Then it's payed and mine and I can sell it. 😊
The QR25DE engine issues were only for a few years (‘02 - ‘04 early ‘05). Later iterations fixed the issues, I had a ‘05 Sentra SE-R Spec V that had zero engine issues and I currently have family members with high mileage Altima’s (‘10, ‘11, ‘13, ‘21) with no engine problems.
4:39 isn't that Fiat Doblo?
Also, Stellantis is rolling with 1.2 Puretech - unreliable construction, problems with oil consumption, timing chains sh*tting themselves after not long distances...
Agree
PureTech, problematic engine
ua-cam.com/video/edNKJ2jyeeU/v-deo.html
Never any problems with Korean built engines! Only US built ones .
Cannot imagine people using incorrect oil is companies fault.
the 2021 sonata shown has a Smartstream engine not a Theta 2. Wrong Car displayed
Nice video...thanks.
You're welcome
Run from the theta 2.4 engines, there's a problem with oil consumption. The 2.0 theta engine doesn't seem to hav the same issues
IMPRESSED! Finally agree with one of these lists. The Nissan qr (quality reduced) probably the best of the lot sadly. The turbo turd 1.0 isn't worth fixing if anything goes wrong. The theta and nu haveade me a lot of money. It's sad, almost all of these have 1 major problems. Their manufacturers cheap out in the wrong areas. But hey they don't want the car to last longer than the warranty. If that was really true there would be no 5.3l Chevy. They make their money upfront or on things other than the engine and for the most parts transmissions. As a mechanic the most consistent engine to go over 300k iss the 5.3l Chevy. Too bad they won't be making them for too much longer with their fuel consumption issues. I can guarantee that every single one of them they ever make will be bought immediately upon announcement if their discontinuation. And then the appreciation $ begins there is really only one way to kill the Chevy.$6plus a gallon fuel.
Thank you
Tellingly, ALL of the engines on this list mainly affect the low(er) cost car models on the market. I can't help but wonder if it's deliberately encouraged by regulators to push marginal buyers out of the market entirely. At the very least, it proves that low end buyers don't matter to the OEMs or government regulators.
But most Honda and Toyota 4 cylinder engines are much better, with very few clunkers. They care about quality and dependability.
Talking about the 1.0L EcoBoost's cool tech and then immediately saying 'wet timing belt' 😂😂😂
That's the kind of 'cool tech' that manufacturers want to avoid at all costs for the reasons you said
Can't agree more
And they should avoid it before ripping our wallet. Our money shouldn't be a test field.
I think all the manufacturers right now are in the process of trying to make every new engine make the current and future worst engines list. It is clear now the manufacturers are ok with compromising reliability and longevity for performance, yes you can get 350hp from a 2.7 inline 4 or 550hp from a 3.0 inline 6 or 1000hp from a 6.2 V8 but you can't have that and get high miles out of it, big lazy V6 and v8s last forever but there is no money in cars lasting forever. Cars are now built to make it through the warranty and be disposed of and that's sad and pretty much a terrible recipe for low carbon footprint. You can take an old gas guzzling car from way back and drive it forever and even with more fuel used and more emissions you still leave a way lower carbon footprint than a new car. And older cars are more recyclable where they have less plastics and toxic materials to dispose of.
Chevy/Buick is going to see the wet belt issue bite them in a few years. All the new Trax and Envista's have them.
I’ve noticed the people who love to dunk on the build quality of American brands are usually in a Hyundai.
I do not understand how these "engineers?" can make this stuff. Any of us with real world experience in repairs knew the wet belt Eco-boost coud not last! For the exact reason they show here. Heat and oil? On RUBBER? It was only a matter of tiem till the belt started to degrade.. The shame is, with an exterior belt, the 1.0 could have been a GREAT little engine
They do it on purpose
One of these things is not like the others. The QR25DE engine is one of the more reliable engines you can get in a vehicle. I'll admit their introduction was rocky in 2002-2006 because they had oil consumption problems but Nissan reworked the engine for 2007 and they have been solid ever since. Hell, the million mile Frontier still had its original QR25 engine.
Those 2.4 Tiger Shark engines in Dodge Darts are hitting 300,000 miles with no problems when you take care of them, so this video claiming they're bad engines is putting out the wrong info to people.
ua-cam.com/video/fRvfrtPR1Bw/v-deo.htmlsi=3xMx3wPd0qHeauL3
Ford ecoboost 2 cylinder belongs in a yard tractor/lawn mower not a car. Avoid anything with a turbo because when they break it gets real expensive real fast.
Thanks for sharing your thoughts. I actually didn’t mention any two-cylinder engines in this video.
Almost all large commercial trucks have turbos and go a million miles plus with no problems. They are a very proven reliable technology. You should only hope the engine lasts as long as the turbo.
@@williamevans2176 And large commercial trucks are related to cars...how???? Another logical failure.
@@Support_Ad_Blocker The original comment was 'Avoid anything with a turbo...' which is nonsense.
@@htimsid no, it's just common sense.
I can't imagine who came up with a wet belt there have been a couple things that are totally stupid ideas in car engines and the biggest idea has to be wet belts and a list of least favourite cars Kia Hyundai Jeep Fiat Ford and Nissan just don't buy them and save you'd self money just buy something decent with a good record of reliability
I’d like to know how squirrels are getting under the hood. Where you add oil, there is nothing but pine cones, leaves and whatever else they eat. I have to be careful cleaning it because I don’t know what that crap could do if it got in the engine. This is the first time it happened. What a mess.
If I had to choose between a Ford Ecoboost, any EV, or being torn up by vicious dogs, I’d ask to see the dogs before I decided. Modern automotive engineers should lose a finger or two each time they design a garbage drivetrain that could likely destroy the financial health of the second owner that thinks their lower mileage vehicle will outlast the payments. They end up paying off a car loan long after the unfixable car went to the salvage yard.
Pretty sure the QR is dead, and has been for a few years. Last thing to have it was the T32 Rogue; the T33 and L34 switched to the PR25DD, though it's only a couple numbers different from the QR on paper.
You go on about these kia hyundai engine but where are they in production ? Not in europe or Asia
My car is 21 year old ford ka and never paid 30 cent to repair any issues
What is it with 2.4 litre engines? I’ve got a 2.4L in my 2011 GMC Terrain. It does worry me. The only major problem so far is a cam sensor that went south. 400$ repair. I don’t know if that’s a good, normal or excessive price.
Neglect,oil changes not done on time.
If that's the same engine as our '15 Equinox, I bought that part at Napa for$30 or so, installed in about 15 minutes.. btw ours drinks oil..
Take good care of it, ahead of manufacturer recommendation. But it is not the one I discussed here, yours is EcoTec engine, I think.
@ 30$ and I spent 400$ that’s not even including the flatbed tow rig ( mine is AWD) I’m also getting peeved with the change oil soon light coming on and this is 20 minutes after an oil change. My mechanic even showed me how to reset the oil remaining after doing an oil change. I’ll never understand GM. Good luck with your Equinox . Take care.
My equinox made 200k miles before I got rid of that curse. I checked my oil every day. Used $30. In oil. a month towards the end.
After five years engines shd be perfected
I don't think so, this looks planned obsolescence and they have to please govt. Or they may leave out the hood for EVs
I had a qr25de in a nissan xtrail. Had an issue with the valve cover leaking. Nissan fixed some of the vibrations by adding a third engine mount...on top of the valve cover. So to change the valve cover (normally maybe 30 min job) took me a week after disassebling the engine mou t to drop the engine down to get to the bolt on the valve cover. Plus the egr valve and the power steering tank. Then the pcv valve snapped and that was 300 dollars australian and 3 month wait. Ended up getting one off ebay for 60 dollars. Horrible gremlin of an engine. Oh and without premium fuel it would only run on 2 cylinders and stall out.
Thank you for sharing your experiences, that is a lot of hassle
I have a Focus with1.0 ecoboost and 200.000 km, with no problem, no power loss, hardly any oil use. So I am curious about the real data of failures, instead of just repeating what other youtubers say (who don 't own a 1.0 ecoboost either).
A lot of complaints, recalls, and lawsuits are not without a reason. Premature failure in an ownership of someone you know is also a good source. I never owned one with any ecoboost.
I got a 2019 F150 FX four eco-boost 3.5 eco-boost 225 miles 00 problem
A wet belt was never ever a good idea not even in theory
Yeah, I have a FCA TigerShark, and have *NONE* of the “problems”. Maybe it’s because I know how tf to drive…
Give it a good care and enjoy it while it is running
Dodge/Fiat hmm what could go wrong ?!?!
Los motores Ingenium y Puretech sobre todo son mucho más problemáticos que el Ecoboost
The QR is a great engine. The throttle body screws was an overblown problem that wasn't really as big as it seemed. It was easily preventable with 45 minutes of labor and the balance shafts really don't ever fail unless you don't maintain the engine. The cat design is stupid, along with like nearly every other Nissan model at the time, and the valve covers DO leak omg do they leak. You have to be careful in your choice of valve covers with them. They have little M6 screws that hold the valve cover onto the engine as well that need to be torqued juussttt right because you will strip out the threads easily. Ask me how I know.
Overall, it's a great engine, makes insane power for what it is, sounds awful but puts the power down so who cares. I loved my QR and am hoping to buy another one again, if they're maintained right and you loctite those 8 screws you're golden
Plus, the 2005+ (I think, I could have the years wrong) went away from the variable length intake runners so you don't need to worry about the screws
For 2yrs.. not a design problem.. poor machining practices..
There is quality control after manufacturing. And quality control people are engineers.
Where are the car companies getting their engineers, makes you wonder, running a timing belt through oil, sounds good, but do they test out any of their "great ideas", GDI, sounds good, but unless you are a meticulous owner about maintenance, and realistically, there's not many, GDI is destined to cause a premature death of your engine, the so called engineers have literally ruined modern vehicles, too much tech, without any reliability.
Planned obsolescence
much as rhe ford ecoboost, the PSA Puretech 1.2 turbo engine is.... also shit..
Source:; i work as a PSA mechanic
Ok dude no. The QR25 is not the only engine that uses a Maniverter (Catalyst thats attached to the exhaust manifold) hell almost every 4 cyl engine does this. Also most also scavenge exhaust. This was a issue with the converters not the engine itself…… the QR25DE also does not have the screws that fall off the throttle plates……. Every engine can have timing chain stretch these motors get abused… and sure yeah the valve cover has to be swapped if the tube seals fail… a hour job at most…. The other engines are common surprised you did not cover the 2.0 ecoboost that had a stupid block deck with the cut that causes head gaskets to fail where the only remedy is just replacing the short block……..
most reliable engines that they dont make anymore because they made too much torque: toyota 5sfe 2.2
I’ve checked the engines listed are US manufactured not from European or Asian countries. US manufacturing is rubbish.
What is with the green screen from 2:34 to 2:54?

Why do recalls always happen after the vehicle has come off warranty?
All ecoboost engines 💩
I found out the hard way😢😢
*except the 2nd Gen 2.7. Seriously, those things are great. The weak link is the wet belt driven oil pump, which I'm pretty sure Ford added (the first generation had a chain driven oil pump) because they weren't having enough service/replacement profit.
1.4 turbo LE2. 150k miles only had a bad fuel injector.
180k kms on 1.6eb. Just did a remap from 180 to 230hp and 240nM to 330nM. Doing only fluids, filters and brakes. And belts when necesary.
They are also nicknamed the ‘EcoBoom’, because that’s the noise they make not long after the warranty expires.

Ford eco boost is not a Ford engine it stellantis psa engine they all have the wet belt issue. Stellantis now have a chain modification
This video is bs.
Who would've ever thought that making an overly complicated 4 cylinder produce more power than it is safe to make. Then putting it in a big heavy vehicle would cause problems? Oh yeah, everybody who understands how engines work.
It's more efficient to have a big engine barely working than a small engine working overtime. Less stress, less maintenance, longer life, and happier owners. This is why I won't own a modern vehicle. I'll stick with my old V8s. Lugging down the highway at 1500 rpm, while the smaller engines around me sound like they're ready to explode. And most probably are
All hyunday new engines are pure shit
The 1.6 Gamma/Smarstream is a solid little simple engine that's mildly overbuilt for the rated power and with correct maintenance is extremely reliable.
I own a 2017 accent with the 1.6 gamma engine It's my daily commuter to work, 180000km and running strong and no oil consumption, but i change oil every 6000 kms using full synthetic oil, gets 50 mpg if driven nicely. Great little engine
